## Price (per second of video, USD)

| Resolution | Price | Credits |
|---|---|---|
| All settings | $0.09 | 9 |

100 credits = $1. Charged once, only for the route that succeeds; failed generations cost nothing.

## Request

POST https://api.revana.si/v1/generations with `Authorization: Bearer $REVANA_API_KEY` and an `Idempotency-Key` header: one key per request, made once and sent again on every resend after a timeout, a 429 or a 5xx, so the request is never made or charged twice. After a generation has failed, use a new key.

```json
{
  "model": "omnihuman-2.0",
  "input": {
    "prompt": "A slow dolly shot through a neon-lit night market in the rain, steam rising from food stalls",
    "image_url": "https://example.com/start-frame.jpg",
    "audio_url": "https://example.com/voice.mp3"
  },
  "max_cost_usd": 1.4
}
```

`max_cost_usd` is your cap, the most this request may cost ($0.09 a second: $0.90 for a 10 s clip). Poll `GET /v1/generations/{id}` until `status` is `succeeded` or `failed`, then download `GET /v1/generations/{id}/content`. Full API: https://revana.si/llms.txt
